Very little labor cost compared to fiberglass. Most of the material comes from recycled plastic garbage. Somehow way more expensive than a fiberglass boat?.. Pull your finger outta your @$$!
I wonder why they only use black plastic? I can see this kind of boat in a cold climate. But I would think that the sun in tropical climates would overheat the material and wear it down or soften it too much. The boat would be very hot because it absorbs so much solar energy? Cool durable boats for some applications.
In another video I believe the builder clarifies that the plastic does not retain heat. Much less than metal or hardened painted surface in any event. Also, I think more colors will be available in the future. When, who knows. Truly wonderful boats with loads of applications.
